Description
Technical field:
The utility model relates to the wireless remote control decoding technique, is specially adapted to anti-decoding telechiric device.
Prior art: beeper is made up of telepilot and main frame at present.Telepilot is made up of encode an integrated circuit and signal transmission circuit and power supply, main frame is made up of receiver amplifier, decoding circuit, mu balanced circuit, operating circuit, mu balanced circuit provides working current for each circuit, the reception amplifying circuit receives the signal of telepilot emission and pass to decoding circuit behind power amplifier, if information code is correct, then decoding circuit instruction works circuit, topworks's work.
At present this kind telechiric device is often illegally cracked by his human demoder and implements the theft vehicle or open the automatic door and window stealing of entering the room.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of anti-decoding of radio telechiric device of dual decoding is provided.
Scheme of the present utility model is: be provided with two coding integrated circuit (IC) 1A, IC2A and all be communicated with radiating circuit in telepilot, be provided with two decoding integrated circuit IC1B, IC2B in the main frame, wherein receiver amplifier is connected with the signal input part of decoding integrated circuit IC1B, decoding integrated circuit IC1B output terminal is connected with the delay switch trigger point, two normally opened contacts of delay switch are connected with the output terminal of decoding integrated circuit IC2B signal input part, signal reception power amplifier respectively, and the output terminal of decoding integrated circuit IC2B is connected with operating circuit.
Advantage of the present utility model is that telepilot must send two information codes at short notice, first information code triggers delay switch work, second information code must be sent in the section in the effective time of delay switch control, could trigger operating circuit by delay switch effectively works, if in delay switch section effective time, can not send second information code, then delay switch disconnects, information code just can't be input to decoding integrated circuit IC2B, then operating circuit can not obtain instruction, makes stealer can't use demoder to crack two information codes at short notice.
Description of drawings:
Fig. 1 is the utility model circuit telepilot block scheme.
Fig. 2 is the utility model host circuit block scheme.
Fig. 3 is the utility model remote control circuitry structural drawing.
Fig. 4 is the utility model host circuit structural drawing.
Embodiment: circuit structure of the present utility model is for being provided with two coding integrated circuit (IC) 1A (700) in telepilot, IC2A (600) is communicated with radiating circuit (800), be provided with two decoding integrated circuit IC1B (300) in the main frame, IC2B (200), wherein signal reception power amplifier (500) is connected with the signal input part of decoding integrated circuit IC1B (300), decoding integrated circuit IC1B (300) output terminal is connected with delay switch (100) trigger point, (100) two normally opened contacts of delay switch respectively with decoding integrated circuit IC2B (200) signal input part, the output terminal that signal receives power amplifier (500) connects, and the output terminal of decoding integrated circuit IC2B (200) is connected with operating circuit (400).
Wherein host power supply is communicated with reception power amplifier (500), decoding integrated circuit IC1B (300), IC2B (200), operating circuit (400), delay switch (100) respectively through mu balanced circuit, so that power supply to be provided, operating circuit (400) is pressed decoding integrated circuit IC2B (200) instruction execution work.
Telepilot has a switch connection coding integrated circuit (IC) 1A (700), and other has the switch of a plurality of selection functions to be communicated with coding integrated circuit (IC) 2A (600).
During work, the signaling person presses first switch of telepilot earlier, make coding integrated circuit (IC) 1A (700) work, IC1A (700) then launches first information code by radiating circuit (800), and after host signal receives power amplifier (500) and receive first information code, pass to decoding integrated circuit IC1B (300), if it is correct to test the sign indicating number comparison, IC1B (300) then triggers delay switch (100) work, then (100) two normally opened contact closed communicatings of delay switch this moment.This moment, the signaling person pressed switch corresponding in a plurality of functional switches of telepilot again by the required function selectivity, and then the coding integrated circuit (IC) 2A (600) of telepilot sends second information code by radiating circuit (800).Main frame receives power amplifier (500) and receives second information code, behind power amplifier, pass to decoding integrated circuit IC2B (200) by the closed normally opened contact of delay switch (100), and decoding integrated circuit IC2B (200) is if test the sign indicating number comparison correctly, then instruction works circuit (400) work, be not inconsistent if test the sign indicating number comparison, then do not make operating circuit (400) work.Decoding integrated circuit IC1B (300) tests sign indicating number and not only triggers delay switch after correct, also optionally be connected simultaneously with warning circuit, if the connection warning circuit is arranged, under the warning circuit state of alert, also can drive the warning circuit that controlled by decoding integrated circuit IC2B (200) and send alerting signal, only alerting signal just can stop after moment decoding integrated circuit IC2B (200) receives correct information code.
After this moment, first information code was sent, if the signaling person can not send second information code in delay switch (100) section effective time, delay switch this moment (100) disconnects, second information code sending out again can't pass to decoding integrated circuit IC2B (200), also just can't work by instruction works circuit (400), it is to decode dicode in moment that stealer illegally uses demoder, thereby ensures the security of this anti-decoding telechiric device.The delay time of delay switch can be arranged in several seconds.
This device can be used for remote control control gears such as the burglar alarm, electric lock, power window of vehicle.
